Fungicide Management Considerations
Research has shown that fungicide treatments can be effective against tar spot. Severe infestations of tar spot may be challenging to control with a single fungicide application due to its rapid reinfection cycle, particularly in irrigated corn. Consider utilizing Aproach® and Aproach® Prima fungicides to help control tar spot.
